public interface Operable<T extends Operable<T>>
extends Realtime

This interface abstracts the fundamental arithmetic operations: plus (+), times (*), opposite (-) and reciprocal (1/).

If the set of objects implementing this interface is commutative under addition and associative under multiplication and the two operations are related by distributive laws, then it forms a mathematical ring (linear algebra). System of linear equations involving these objects can be resolved using the Matrix class.

Method Detail

plus

T plus(T that)

Returns the sum of this object with the one specified.

Parameters:

that - the object to be added.

Returns:

this + that.

opposite

T opposite()

Returns the additive inverse of this object. It is the object such as this.plus(this.opposite()) == ZERO, with ZERO being the additive identity.

Returns:

-this.

times

T times(T that)

Returns the product of this object with the one specified.

Parameters:

that - the object multiplier.

Returns:

this * that.

reciprocal

T reciprocal()

Returns the multiplicative inverse of this object. It it the object such as this.times(this.reciprocal()) == ONE , with ONE being the multiplicative identity.

Returns:

ONE / this.
